Blowing sockets and popping RCD

[Josh555]

A client asked me to add two sockets in their bedroom

I took power from two sockets in the lounge which is behind the bedroom wall.

I ran a cable out of each socket for the new socket

The problem is it now is tripping the RCD and blowing the old Existing sockets and light switches

But the new sockets I added still work fine

The old existing sockets and switche are blown and unusable

When I try to reset the RCD It pops and Sparks down

Any idea to why this is happending

 

[littlespark]

if the old sockets were on a ring, and one leg has popped out... the new sockets, being connected will still work, but theres maybe another floating live touching the metal back box.

can you take photos of the back of the sockets? there might be something obvious to us that you havent seen

The thing is the client phone back saying there’s no power and the RCD is popping down and sparking so I went back same night, and opened up the sockets I touched the connections were fine the socket sparked and popped while the socket was open so no loose lives

Sockets "blown"?!! What does that mean?!

 

[mattg4321]

What are your IR results for that circuit?

Good luck

The actual sockets I took power from sparked an blew

The wind blows. You mean the mcb tripped off? If that happened there's no way the new sockets could be still live

no the actual sockets sparked and blew in front of me
The mcb never tripped once only the RCD

 

[goasis]

I still dont know what you mean. But anyway, if the RCD tripped the other sockets def were not still live. Did you do any testing?

 

[Josh555]

What are your IR results for that circuit?

No tests on the ring were carried out

 

[mattg4321]

No tests on the ring were carried out

So how do you expect to find the problem without testing? Apologies if I’ve got the wrong end of the stick here, but if I’m dealing with a symptom of tripping pretty much the very first thing I do is IR testing

No testing

On the assumption you're trained and experienced, what does that tell you ?

so I went back same night, and opened up the sockets I touched, the connections were fine, the socket sparked and popped while the socket was open so no loose lives

Did you leave the socket sparking and popping when you left or have you isolated it / them?

 

[Dave OCD]

Well with all due respect you'll be hard pushed to get much help with that admittance, not good.

 

[goasis]

Going back to your original question, "any idea as to why this is happening " I'd suggest it is because you are vastly underqualified/experienced to be carrying out this work. The fact you called the customer a client suggests you are being employed to carry out this work which you probably shouldn't be doing and are probably at risk of endangering property and life.

 

[westward10]

From your profile I see you are a trainee so is this a private job?

 

[Josh555]

On the assumption you're trained and experienced, what does that tell you ?



Did you leave the socket sparking and popping when you left or have you isolated it / them?

Yes they were isolated the socket was removed completely and connections put into a choc box

 

[westward10]

Are you doing this as a private job?

don't have much experience with fault-finding so that's why I'm asking that question. I've been doing electrics for 2 and a half years

 

[Josh555]

Are you doing this as a private job?

Yes

 

[westward10]

In this day and age it is a bad idea to undertake such works without the necessary experience and insurances. Unless you know someone who can help you your 'client' needs to seek the services of an electrician and you are likely to foot the bill, a harsh lesson but you don't have much choice.

I'm an apprentice with 2 and a half years experience I work for a company we call all our (customers) clients thank you. I have completed electrical tasks 10x harder than this one anything from 2-3 way switching to DB uprgrades. I have done the above countless of times without problem.

Understood I do have someone with the necessary experience and qualifications who has seen be do this type of work so many times. So they know I can do it correctly.

eDo you know what IR testing means????

 

[goasis]

Right, to clarify:

-You spurred off 2 sockets to add in 2 additional sockets
-Assume they were OK when you left?
-Now the sockets you spurred from are 'sparking' and "blowing", (still don't know what you mean by this)
-The rcd is tripping
- but the new sockets are still live? There's no way the rcd can trip, and your new sockets still be OK. There's only one rcd covering all the circuits.

 

[westward10]

I don't know what has happened here but from you you are saying you don't have the knowledge to interpret what has happened. It is all very well undertaking things '10×' harder than this but you must have introduced a fault, it happens to us all but experienced people can normally resolve the issue.

Insulation resistance. I'm not a newbie dummy so stop asking these dumb questions I just don't have 10byears experience

Dude, don't get offensive, you've attempted to undertake a fairly basic task, somehow created a fireworks show. Don't be surprised if you get asked "basic" questions.

No so basically the the sockets were working perfectly fine when I left use my kewtech socket tester. Client phone back about 6-7 hours later saying the RCD was popping and tripping the mcbs never went down once only the RCD. I then opened up the sockets I added the connections were fine. I then opened up the sockets I spurred of from connections were fine. The light switch then popped this was busted then the socket I took power from physically blew with sparks. Alot of the old switches and sockets blew but My new sockets were fine. I know this because I removed the sockets I took power from and put the connections in wagos and everything worked fine.no more tripping
